Application filed April 8, 1913. Serial No. 759,740.

' erence to an improved plow head and clevis,

whereby the front en of the plow beam may beadjusted vertically and laterally with respebt to the draft for the purpose of gaging the depth and theamount of land taken by the plow.

The principal object-of the invention is to produce a simple and efiicient device whereby the required adjustment of the plow may be eiiected i'na simple and convenient manner without the use of special tools.

A further object of the invention is to provide a simple and improved construction whereby the parts of the device will be firmly secured when properly adjusted and assembled.

' With these and other ends in view which Will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts -which will be hereinafter fully described and particularly pointed out in the claim.

In the accompanying drawing has been illustrated a simple and preferred form of the invention, it being, however, understood thatno limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claim may be resorted to when desired.

in the drawing. Figure 1 is a top plan fview showing the front end of a plow beam equipped with the improved appliance. Fig. 2 is a side elevation of the same. Fig.

,3 is a vertical transverse sectional view taken on the line 33 in Fig. 1. Fig. 4 is a perspective view of the pin or connecting member detached.

Corresponding parts in the several figures are denoted by like characters of reference;

The front end of the low beam 6 carries a head which in the il ustration is shown as being cpm osed of two cheek plates 7 l. whichare bo ted .or otherwise procured on opposite sides of the beam in advance of which the said check plates project divergcntly. Each check plate is provided with a vertical slot 8, the side walls of which are provided with recessesiorming a plurality of spaced approximately circular, enlargements or openings 9 for the passage of a key member consisting of a bolt 10 which is of a diameter corresponding to that of the enlarged openings 9. Said bolt is also provided with flattened portions 11 which are suitably spaced apart so that by placing the said flattened portions in registry with the slots 8, the bolt may be moved Iongi tudinally of said slots, that is to say, vcn tically with respect to the plow beam to various positions with respect to the beam. When the ropcr ad'nstment has been reached the Mt may e moved until the round portion thereof coincides with some of the openings 9, thereby preventing a further displacement of the bolt longitudinally of the slots4 A clevis member 12 is provided consisting of'a horizontally disposed plate having a longitudinal slot 13 having approximately circular enlargements 14 at intervals throughout its length. The plate or clevis member 12 is provided with apcrtured lugs 15 engaging the bolt 10 adjacent to the outer faces of the cheek plates, and one of said lugs includes a, laterally extending apertured flange 16. The bolt 10 is provided at one end with a cotter pin 17 and at the other end with a resilient latch member 18 engaging the eye member 16. The bolt is also provided with a head having an eye 19 which forms a handle whereby it may be manipulated and within which the handle portion 20 of the latch 18 is accommodated.

The clevis member 12 carries a pin or bolt 21 having a head 22, a stop member such as a cotter pin 23 and a flattened portion 24, which latter, when the slot 13 will permit said bolt to be moved longitudinally of said slot, that is to say, transversely with respect to the plow beam. The bolt 21 may serve to support a draft attachment, such as an ordinary evener, such draft attachment being thus connected with the plow.

It will be seen frbm the foregoing description taken in connection with the drawing that when the arts are pro erly assembled for o ration, t e in r be t 21 will be re tain" in position y avity. .The bolt 10,

placed in registry with lnm 'ever which would be liable to displacement by 'ibration when the device is in operation is retained securely by mcansiot' the spring latch 18. To cttogat vertical adjustment of the draft with respect to the plow beam, the head of the bolt 10 is grasped and the latch handle is pressed to disengage the latch from the eye member 16 when the bolt may readily be moved to place its flattenedportions in registry with the slots 10, after which the requisite adjustment may be made and the bolt restored to its .initial position. In like manner, by lifting the bolt 21 until its flattened portion 24 is in registry with the slot 18, the bolt may be moved 1ongitudinally of the slot and afterwards restored to its initial position. These operations may be performed very easily and rapidly and without the use of special tools of any kind. This is especially advantageous because at the'beginning of plowing operations it is frequently necessary to readjust the parts a number of times until the exact adjustment desired is had. The improved device permits such adjustments and readjustments to be performed without loss of time and with out annoyance caused by the absence of tools.

Having thus described the inve-ititm, what is claimed as new, is

A plow head comprising cheek plates having vertical slots provided at intervals with approximately circular enlargements, a bolt extending through enlarged portions of the slots and having flattened portions that may be placed in registry with the slots, a clevis member carried by the bolt, a stop member at one end ofthe bolt, a head at the other end of the bolt, said head having an eye, and a spring latch connected with thebolt and having a handle extending within the eye, said spring lltCll being adapted to engage the clevis member to thereby retain the bolt in adjusted position.

In testimony whereof I afiix my signature in presence of two witnesses.
